METHO OF MAKINGWELTING 0B THE LIKE.

Application led January 11, 1927. Serial No. 160,444.

The present invention relates to boots and. shoes and more particularlyto welting and the method of making welting and the mainobject of theinventlon is the economical treating of leather'strips to form weltlnghaving the desiredcharacteristics. y y A further object of the inventionis the economical manufacture of welting of the caulk or water-prooftype. p

Another object of the invention is theprovision of a welt having aserrated edge.

Other objects of the invention will be apparent from the followingdescription.

According to the present invention a strlp of leather or equivalentmaterial is cut on both sides of a longitudinal median line and stripsof leather of substantiallyrectangular cross section are removed leavingthe strip of leather having a longitudinal central rib. The strips ofleather thus removed may be used in the manufacture of boots and shoesas is well known to those skilled in this art. The remaining strip isthen cut into two strips' preferably of equal width thereby producingtwo strips of identical characteristics, each of Ithese strips havin amarginal raised or flanged' portion the e ge of which being subsequentlysubjected to an ironing by a heated roller to impart to the lesh portionof the leather the appearance of the grain portion. y,

According to one form of the invention, the centrally ribbed strip issubjected to the action of a cutter which simultaneously divides thestrip into two welt pieces as above described and also imparts to theedge of the marginal flange a serrated surface.

For amore completeunderstanding of the invention reference is to be hadtothe following description and to the accompanying drawings forming apart of this specification.`

vIn the drawings Fig. 1 is a fragmentary view of a strip of' leather orthe like; v v

Fig. 2 is a view of the strip shown in Fig. 1 after the first operationhas been performed; v

Fig. 3 is a view of the centrally ribbed strip divided into two weltpieces of identical characteristics each having amarginalv flange theedge of which is serrated; Y

Fig. 4 is a view of single welt piece having a marginal iiange with aserrated edge Fig. 5 is a view of the centrally ribbed strip dividedinto two welt pieces of identical characteristics each having a marginal'fiange with a plane surface; v

F1g. 6` 's a view of a single welt piece having a mar inal flange theedgeof which is a plane sur ace;

Fig. 7 is a sectional view of a shoe having the serrated edge caulk weltshown by Fig. 4 applied tothe shoe so that one side of the caulk weltlies liat on the usual welt; and

Fig. 8 is a view similar to Fig, 7 but shows theserrated edge caulk weltapplied to the shoev so that one side abuts the shoe upper and theotherlside is at an angle to the usual welt.

Referring to thedrawings in detail, Fig.

1 shows a fragment of a strip of leatherwhich is subjected to thehereinafter described process to produce the strips of the desiredcharacteristics. The strip 10 is iirst treated to remove therefrommarginal strips of substantially rectangular cross section leaving astrip llfg shown by Fig. 2, having a central rib 12.

The strip 11 is then ldivided into two pieces 13 and 14 of substantiallyidentical characteristics, each of these stri s comprising a welt piecehaving a margins.V raised portion or flange 15 the edge of which isserrated as designated by the reference i character 16. The cutteremployed for dividing the ribbed strip 11 is such as to simultaneouslyform the flanges 15 with the serrated edges. Fig. 4 shows a strip orwelt piece having a flange with a serrated edge. In my co-pendingapplication, Ser. No. 160,443, filed January 11, 1927 I have shown animproved machine for simultaneously dividing the strip 12' or,`

a similar strip and serrating the edge of the resulting il'anged weltpiece.' i

The stri 1-2 may be divided into two weltl pieces as s ownl by Figs. 5and 6, each of the welt pieces having Va marginal flange the edge ofwhich is substantially a plane surface.y For this purpose the strip 12is cut along its longitudinal median line forming two strips-,17 and 18leach having a mar 'nal flange 19. The edge of the marginal ange maysubsequently be subjected tothe ironing action of a heated roller forimparting thereto the appearance of theJ grain side of the leather.

, Fig. 7 shows a welt piece 13 or 14 a plied,

to a shoe. The flanged portion 15 lies at on the Goodyear welt 20 andabuts the shoe upper. Fig. 8 shows the welt piece applied to the shoe sothat the flange portion abuts the shoe upper and is at an angle to theGoodyear welt 20. It is thus apparent that the appearance of the shoemay be chan ed terial. While the strips 13 and 14 are shown such as thestrip 10 maly as ianged it will be understood that a strip be dividedalong a longitudinal margina line by a cutter which also serrates theedges of the resulting strips. It is preferred, however, to form thewelt pieces with marginal flanges as shown Fig. 4. l While I have shownand described the preferred embodiments of the invention, it is to beunderstod that certain changes may be made without departing from theinvention as dened by the appended claims.

Having thus described the invention, what I claim and desire-to secureby Letters Patent of the United States isz- 1. The method of treating astrip of leather or the like to form a plurality of welt piecescomprising removing from a face of said strip adjacent both of itslongitudinal edges strips ,of substantially rectangular cross sectionleaving a strip having a longitudinally extending central rib anddividing said ribbed strip along a longitudinal median line forming twowelt pieces of idenv tical characteristics.

. 2. The method of treating a strip of leather or the like toform aplurality of welt pieces comprising the step of removing from a face ofsaid strip adjacent both of its lon'- gitudinal edges strips ofsubstantially re- The strips 13 and 14.

tangular cross section leaving a strip having an intermediatelongitudinally extending rib.

3. The method oftreating a strip of leather or the like which stripsadjacent both longitudinal edges thereof leaving a strip that is thickerat its central portion than at its edges, and dividing said strip alongits longitudinal median line forming two welt pieces.

4. The method of treatin a strip of leather or the'l'ike to form a plurait of welt pieces comprising the removing o strips from a face thereofadjacent both longitudinal edges leaving a strip having a longitudinallyextending rib intermediate the edges of said strip, and simultaneouslydividing said strip throu h said rib along a longitudinally exten ingdividing line and serrating the edges of the resulting strips'adjacentsaid dividing line.

The method of treating a strip of leather or thelike to form a plurality of welt pieces comprising removing stripsadjacent both longitudinal edges leaving a strip that' is thicker at itscentral portion than at its edges, and simultaneously dividing saidstrip along a longitudinal median line and serrating the edges of theresulting strips.

6. The method of treating a strip of leather or the like comprising thestep of reducing the thickness of the strip near its longitudinal edgesleaving a strip that is thicker at its central portion than at itsedges, and dividing said strip longitudinally through said thickerportion.
